TO ALL WHOM IT MAY CONCERN Be itkuown that i, OL L. GARDSIElnoi' the city. county, and State oi' New York, have invented a. new and useful improvement in Frames for Mirfi'ors, etc.; andI do hereby declare that the following'is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had .to the accompanying drawings, forming part of this sp'eciication. I

The present invention principally consists in constructing a frame for mirrors, etc., in such a manner that its side pieces can be adjusted either neareruto or farther from eachother, and there set, according to the size of the glass, etc., to be placed therein, within certain ranges or limits, whereby frames can `be made or built as to be more generally adapted for the reception of mirrors of var vin:r widths. In the accompanying plate of drawings my improvements in frames for mirrors, etc., are' iliustratedy Figure l being an elevation of a frame; constructed according thereto. from its rear or back side.

Figure 2, a transverse section, taken inthe plane of' the line :c :12, fig. l.

Figure 3, a. view ofthe under side to the lower cross-railor bar oi' the frame; and

Figure 4 a view in detail on an enlarged scale.

Similar letters of reference indicate corresponding parts.

A, in the drawings, represents a frame made according tothe present invention; to which frame A, B is the lower cross-bar or rail, and C the upper cross-piece or rail, both of which may be ornamented in any suitable manner, and otherwise constructed for beautynnd effect, as maybe desired. These bars B and G are joined together by-side strips'D, the length of which may be either more or less` as may be requisite or found practicable. These strips D, in'lieu of being fixed at each end to the upper and lower rails B and C, are arranged to slide therein toward and away from each other, s'o as to reduce or increase the width or space between them according to the width of glass, etc.. the frame is to receive, within certain limits. These side strips D at each end have set-screws E, that project through slots in the upper and lower crossbars B and C, and extendinl in the proper direction for the movement of thc strips toward or away from each other.- By tightening these set-screws the sides D can. be secured in any position put. To facilitate the adjustment of the sides D with regard to each other, graduated plates F are fixedl to the bars B and C, in proper position therefor, the graduations of which are tc be numbered as 'may be found most desirable for the special purpose to which the frame is to be applied, as for instance with mirrors, by the gures 20, 22, 24, as by them are indicated .the difference in width of the sanie length of glass. Along the inner edges of' cach of the side strips u. groove, a, is made, that in cross-section is upon one side, b, berelled or'inclined so that the edge of the glass can be wedged thereon, whereby the use of wedge-blocks is dispensed with, anda more convenient and reliable fastening secured. i

I claim as'new, and desire to secure by Letters Pnt-entt 1. Aframe for mirrors, Ste., in which the side pieces are arranged to be adjusted with reg-ard to each other, substantially as and for the purpose described.

2. I also claim the groove or rabhet a, having bevelled side pieces arranged for adjustmenof a frame for mirrors, etc., substantially as and forthe purpose described.

The above specification of my invention signed by me this 25th day of June, 1867.
